To all whom it may concern:

Be it' known that I, JAMES A. ALLISON, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Regulator-Valve for Compresshm Tanks; and I do hereby declare that the fol lowing is a full, clear, and exact description thereof, reference bcin led to the accomanying drawings, in which like numerls reer to like parts.

The object of this invention is to improve the valve and gage construction connected with the outlet of compression tanks.

The invention has been usedin connection wlth ac'etylene gas tanks for automobiles.

One feature of the invention consists in .(connecting the service or line pipe with the tank by means including a plurality of independently operable valves, one to regulate the outlet from the tank and the other the inlet to the service ipe, whereby the outlet from thetank may lie closed without changin or interfering with the adjustment of the valve which controls the inlet into the service .or line pipe, 1

Along with the foregoing a further feature of the invention consists in making the two valves readily detachable, whereby the tank may be'removed and be recharged or replaced without interfering with the adjustmen of the valve that controls the passage of the fluid to the service or line pipe.

Another feature of the invention consists in combining with the parts above mentioned .a pressure age located intermediate the two valves so t rat the fluid under pressure com ing from one valve acts upon the gage before it reaches the second valve, whereby the gage will indicate the pressure of the lluid in the tank and the outlet of the fluid from the tank, and when the outlet of the fluid from the .tank has shut, oil the gage will be idle and not under strainand the adjustment of the valve controlling the inlet to the line pipe will be unchan ed. To this end, between the said valves I locate a thrce-way chamber, an opening leading thereto from the first valve,

' another opening to the gage and a third mg or replacing.

The nature of this invention will be under-- stood from the accompanying drawings and the following description andclaims.

In the drawii igs Figure Iiis a side elevation of an acetylene gas tank with my valve and gage construction secured thereto. Fig. 2 is a plan view oltho left hand end of Fig. 1. Fig. 3- shows the left hand end of the tank and the valve controlling the outlet therefrom, as shown in Fig. 1 and as the same will appear when the tank is removed for recharg- Fig. 4 is a central vertical section through the valve mechanism and adjacent parts as arranged in Fig. 1,the tank and line pipe being partly broken away. Fig. 5 is a transverse section on the line 5-5 of Fig. 4, showing the gage in elevation. Fi 6 is the lower part of Fig. 4 with the va ve nearly closed for regulating the passage and pressure of fluid to the line pipe and showing the partsas they appear when the tank and tank valve are moved. Fig. 7 shows the upperpa-rt of Fig. 4 withthe tank valve closed and with the parts as they appear when the tank and tank valve are detached.

In the drawings 10 represents an acetylene gas tank, 11 the gas tank valve controlling the outlet of fluid from the tank, 12 the easing for the gas tank valve which is secured to the gas tank, 13 the pipe line valve, 14 the casing for the pipe line valve which at one end is secured. to the casing of the gas tank valve and at the other end to the line pipe 16 is a pressure gage which is secured to one end of the casing 14 of the pipe line valve. In detail there is a threaded opening 20 in one end of the tank which receives the threaded nipple oi the casing 12 ol the tank valve, there being a. relatively large passageway 21 a diminished passage-way 22, a conical valve seat 23, a chamber 24, and a down wardly extending large passage-way 25 in said casing 12.

The valve 11 is a needle valve which screws through the outer end of the casing 12 on wliichtlieie is a suitable packing ca 26.

The casing 14 for the pi e line va vs 13 has threaded to screwinto the service pipe 15. A union 34 connects the nipple 33-with the casing 14 and 'said nipple "33'has a narrow passage-way 35=that leadsfromthe passages way 31 in the valvecasi-ng 32 tethe. pipe-g to secure by Letters. Patent isz."

line 15. I

The valve 13 is a-needlevalve formed, ar ranged and mountedlike the-valve 11 andadapted to close the valve seat36 at the end.- of ,the narrow' passage-way 37, that leads troma substantially rectangular chamber 38 in the substantially rectangular-end 39 of the valve casing 14. p r I The two valve casings 1'2 and 14 are connected by the nipple 40 that has a conical upper. end projecting intojthe downwardly extending nipple from the casing 12 and which is externally threaded at its lower end 'to screw into the rectangularend 39 of the casing 14. A union 41 connects the nipple 40 with the lower end of the valve casing 12. A narrow passageway. 42 extends through the nipple l0 and leads from the passage-. way 25 above into the rectangularptrssageway 38-below. This renders the valve casing 12 readily removable from the valve casing 141 by loosening the union 41.

The gage .13 has an externallythreaded tubular shank that screws into one side of the rectangular end 39 of the casing 14 and hasa passageway 51 through it that leads from the chamber 38 t0 the gage. Therefore, the chamber 38 is a three-way chamber, there being a passage into it from the tank through the tankvalve. casing, a passageway out of it to the linev pipe through the line pipe valve casing, and a passage a m another sideto the gage. There is also a removableplug '52 closing an enlarged opening into the end 39 of the casing 14-, HS?" shown in Fig. 5, which renders said .chamber accessible or permits a change of location of the gage.

From-the foregoing description it will be plain thatthe parts may be turned andadjusted in any position that the location of the tank and other mechanism may require,

which make the device universal in use It alsoseen' that the. valve 11 controls the admitting the desired quantity of fuel to the pipe line under the desired pressure to produce the desired light, and thatwhen said valve s so adpisted. it may-remain n such adjusted position'when the tank valve is closed entirely, while thcepparatusis not inuse, or when the tank is being removed, recharged or replaced. Furthermore, whom the pipe line, and this sbrought about by an valves provided with three openings for the tiuidentering thesame. I
